Zac, its been my experience that early shedding/early growing bucks can get a great head start growing antlers from May through to hard antler. But, having said this, I havent seen where late shedding bucks get behind. They just seem to grow later into the summer when others have already finished up. I had a decent buck shed both antlers on April 11th three yrs ago. That fall he had his biggest antlers to date. So, to answer you, it didnt seem to matter that he was running behind to begin the spring.
